Figure 2
Polyhedral representation of KAlSiO4 substructures a (upper row) and b (lower row). Single tetra­hedral layers (built-up from the S6R units) are projected along c with AlO4 (dark grey) and SiO4 (light grey) tetra­hedra. K atoms are represented by grey spheres. For both substructures, the stacking of the layers with respect to the unit cell is represented projected along b.
